#CVE-2021-43536: URL leakage when navigating while executing asynchronous function Reporter Sunwoo Kim and Youngmin Kim of SNU CompSec Lab Impact high Description Under certain circumstances, asynchronous functions could have caused a navigation to fail but expose the target URL. References Bug 1730120 #CVE-2021-43537: Heap buffer overflow when using structured clone Reporter bo13oy of Cyber Kunlun Lab Impact high Description An incorrect type conversion of sizes from 64bit to 32bit integers allowed an attacker to corrupt memory leading to a potentially exploitable crash. References Bug 1738237 #CVE-2021-43538: Missing fullscreen and pointer lock notification when requesting both Reporter Irvan Kurniawan (@sourc7) Impact high Description By misusing a race in our notification code, an attacker could have forcefully hidden the notification for pages that had received full screen and pointer lock access, which could have been used for spoofing attacks. References Bug 1739091 #CVE-2021-43539: GC rooting failure when calling wasm instance methods Reporter Asumu Takikawa and Ioanna Dimitriou Impact high Description Failure to correctly record the location of live pointers across wasm instance calls resulted in a GC occurring within the call not tracing those live pointers. This could have led to a use-after-free causing a potentially exploitable crash. References Bug 1739683 #CVE-2021-43541: External protocol handler parameters were unescaped Reporter chriscla Impact moderate Description When invoking protocol handlers for external protocols, a supplied parameter URL containing spaces was not properly escaped. References Bug 1696685 #CVE-2021-43542: XMLHttpRequest error codes could have leaked the existence of an external protocol handler Reporter Raphael Smolik Impact moderate Description Using XMLHttpRequest, an attacker could have identified installed applications by probing error messages for loading external protocols. References Bug 1723281 #CVE-2021-43543: Bypass of CSP sandbox directive when embedding Reporter Armin Ebert Impact moderate Description Documents loaded with the CSP sandbox directive could have escaped the sandbox's script restriction by embedding additional content. References Bug 1738418 #CVE-2021-43545: Denial of Service when using the Location API in a loop Reporter Paul Zühlcke Impact low Description Using the Location API in a loop could have caused severe application hangs and crashes. References Bug 1720926 #CVE-2021-43546: Cursor spoofing could overlay user interface when native cursor is zoomed Reporter Daniel Veditz Impact low Description It was possible to recreate previous cursor spoofing attacks against users with a zoomed native cursor. References Bug 1737751 #MOZ-2021-0009: Memory safety bugs fixed in Firefox 95 and Firefox ESR 91.4 Reporter Mozilla developers and community Impact high Description Mozilla developers and community members Julian Hector, Randell Jesup, Gabriele Svelto, Tyson Smith, Christian Holler, and Masayuki Nakano reported memory safety bugs present in Firefox 94 and Firefox ESR 91.3. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code.
